Abstract

The utility model discloses a nano-ceramic electrode lamp, which aims at providing a nano-ceramic electrode lamp with low energy consumption, long service span, uneasy oxidation, brittle fracture and wire breaking, and supernormal switching times. The nano-ceramic electrode lamp comprises a transparent ceramic discharge pipe which closes a discharge space and is closed by a ceramic plug, and an electrode component formed by winding on a ceramic discharge pipe molybdenum coil, wherein the electrode component is respectively connected with a lead wire thereof through a retaining bracket and a lamp socket which are fixed on the upper end of a glass casing and through an electric current conductor feedthrough line. The nano-ceramic electrode lamp has high lumen ratio, slow light decay, high light efficiency, low energy consumption, long service span and uneasy oxidation, accords to the concept of green lighting, and solves the problems that a traditional metal tungsten filament electrode lamp consumes electricity and has short service span.

Description

Nano ceramic electrod lamp

Technical field

The utility model relates to a kind of lamp and light fixture thereof with sealing discharge space that be mainly used in, and comprises the electrod lamp in the discharge tube.

Background technology

Common metal tungsten filament electrode lamp of the prior art, the easy oxidation of its metal tungsten wire electrode, embrittlement, fracture of wire and its electronics emission powder body material come off and sputter easily.It causes the fluorescent lamp two ends to be turned black to life termination because therefore each switch all will, usually cause the electronics powder to break away from its metal tungsten wire matrix through the physical process that heating is expanded, cooling is shunk.The easy oxidation of metal tungsten wire electrode, embrittlement, fracture of wire and its electronics emission powder body material come off easily and the shortcoming of sputter extremely short its useful life.

Summary of the invention

Propose on the purpose of this utility model a kind of simple in structure, low power consuming, long-life, be difficult for oxidation, embrittlement, fracture of wire, have the nano ceramic electrod lamp of extraordinary switch number of times.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of nano ceramic electrod lamp, have one and have lamp socket and inert gas filled glass shell, it is characterized in that, it has the transparent ceramic discharge tube of a sealing discharge space, this ceramic discharge tube is sealed by ceramic plug, one is wrapped in the electrode assemblie that described ceramic discharge tube molybdenum coil is formed, and electrode assemblie links to each other with its lead-in wire with lamp socket by the holder of glass shell upper end respectively by current conduction body feedthrough line.

The beneficial effects of the utility model are that simple in structure, cost is low.The utility model utilizes characteristics such as ceramic-metallic high strength, high temperature resistant, corrosion-resistant and low bulk, overcome the shortcoming of the easy oxidation of metal tungsten wire electrode, embrittlement, fracture of wire, has extraordinary switch number of times.Because the discharge tube of ceramet electrod lamp is made up of the transparent ceramic pipe, compare with quartz ampoule and to have unrivaled superiority, but the temperature of earthenware Nai Genggao (fusing point exceeds more than 500 degree than quartz), therefore fluorescent tube can be operated under the higher load, makes light fixture that higher efficient and better photochromic performance be arranged.But earthenware is the erosion of halogen resistant and highly basic metal at high temperature, makes the photoelectric properties of lamp have better stability and longer life-span.Therefore have lumen rate height, light decay is slow, and light is efficient, low power consuming, and the long-life, be difficult for oxidation, meet the green illumination theory.Solved the power consumption of conventional metals tungsten filament electrode lamp, the problem that the life-span is short.
